Do you dig?
"Does to dig mean 'to like', 'to understand' or 'to appreciate'?"
"Well, you know music. It's like the quarter-note in music. You know... the note between C and C-sharp, with its own identity. Its own sound. Because you can't call it C or C-sharp....Dig is like that. Dig means dig."
"....You mean that dig not only means that I understand, but that I am a special sort of person who understands in his own special way."
"Yeah, exactly. I dig."
